This patch fixes a bug in VPI systems, where the first port is

the rdma_id isn't bounded to a port, cma_match_net_dev will try to
verify that the first port is a RoCE port and fail. This is fixed by
passing the port of the incoming request.
OK -- we have another bug down there, cma loopback doesn't work, same
reject reason (below).This happens in both VPI and non-VPI
configurations.
Works well with 4.2.3
I made more checks with the 4.2.3 kernel (before all the IB core/cache
changes that went in 4.3) -- rdma-cm loopback does work as long as there
are active IB ports in the system. When there are no active IB ports,
but rather only Eth ports (VPI or plain Eth), rping fails:
# rping -d -v -c -a 127.0.0.1 -C 1
created cm_id 0x6087d0
cma_event type RDMA_CM_EVENT_ADDR_RESOLVED cma_id 0x6087d0 (parent)
rdma_resolve_route: No such device
so it seems we had something there before the 4.3 changes.
Or.
